I have not tried the flat films but thanks for the warning. I have been using Doculam almost exclusively and painting but I always had paint adhesion issues. I am still experimenting, my latest attempts with Doculam is using flexible acrylic paint designed for use on clothing.

This P-51B is actually an ARF (not at all almost ready to fly though) from E-Flite but I posted this question here because it is a finishing question that relates to kit or scratch building. I am impressed with E-Flites ARF's though and this kit is gorgeous. It looked pretty bad with the glossy Ultracote but my hat is off to E-Flite because they actually included in their build instructions the procedure for using the dullcote and using the chalk pastels for weathering.

My main concern on finishing this one was touching up the Ultracote once the finish was on and how to add panel lines.
